The Museum of Contemporary Art in Los Angeles spared no expense for its 30th anniversary celebration over the weekend. Lady Gaga performed her new ballad, "Speechless" in an art-meets-entertainment spectacle masterminded by Italian artist Francesco Vezzoli. The production featured a dance by the Bolshoi Ballet, Gaga on a pink piano painted with butterflies by Damien Hirst, and costumes by Miuccia Prada.

Hosted by POP magazine's Dasha Zhukova and Larry Gagosian the event was attended by 1,000 guests from the worlds of fashion (Carine Roitfeld, Cameron Silver, Kate and Laura Mulleavy), art (Takashi Murakami, David Hockney, Jeff Koons), music (Gavin Rossdale and Gwen Stefani), and film (Angelina Jolie, Brad Pitt, James Franco).

"My wish is that the entertainment industry makes love more often with the art industry," said Vezzoli of the production. "I love that," replied Gaga. "Having my fans watch the [performance] video and be exposed to a level of art and a level of installation is so beautiful and so important."
